Emma - Volume 1 (Chapter 5, page 1 of 8)

"I do not know what your opinion may be, Mrs. Weston," said Mr. Knightley, "of this great intimacy between Emma and Harriet Smith, but I think it a bad thing."

"A bad thing! Do you really think it a bad thing?--why so?"

"I think they will neither of them do the other any good."

"You surprize me! Emma must do Harriet good: and by supplying her with a new object of interest, Harriet may be said to do Emma good. I have been seeing their intimacy with the greatest pleasure. How very differently we feel!--Not think they will do each other any good! This will certainly be the beginning of one of our quarrels about Emma, Mr. Knightley."

"Perhaps you think I am come on purpose to quarrel with you, knowing Weston to be out, and that you must still fight your own battle."

"Mr. Weston would undoubtedly support me, if he were here, for he thinks exactly as I do on the subject. We were speaking of it only yesterday, and agreeing how fortunate it was for Emma, that there should be such a girl in Highbury for her to associate with. Mr. Knightley, I shall not allow you to be a fair judge in this case. You are so much used to live alone, that you do not know the value of a companion; and, perhaps no man can be a good judge of the comfort a woman feels in the society of one of her own sex, after being used to it all her life. I can imagine your objection to Harriet Smith. She is not the superior young woman which Emma's friend ought to be. But on the other hand, as Emma wants to see her better informed, it will be an inducement to her to read more herself. They will read together.
